Abstract
A method for constructing velocity models for stacking seismic data, or, more generally, a method for determining reflection geometries with seismic gathers through the use of trace-to-trace coherency coupled with global editing capability to separate velocity events corresponding to primary reflections from multiple reflections and other noise. A velocity model can be fit to the edited velocity events and used for stacking of seismic data. Alternatively, the measured reflection geometry has other potential uses including providing data to be input to a tomographic velocity updating procedure that produces a migration velocity model.
